Also partially revert the follow-up change "drm: pl111: Absorb the external register header". This reverts the parts of commits 7e4e589db76a3cf4c1f534eb5a09cc6422766b93 and 0fb8125635e8eb5483fb095f98dcf0651206a7b8 that touch paths outside of drivers/gpu/drm/pl111. The fbdev driver is used by Android's FVP configuration. Using the DRM driver together with DRM's fbdev emulation results in a failure to boot Android. The root cause is that Android's generic fbdev userspace driver relies on the ability to set the pixel format via FBIOPUT_VSCREENINFO, which is not supported by fbdev emulation. There have been other less critical behavioral differences identified between the fbdev driver and the DRM driver with fbdev emulation. The DRM driver exposes different values for the panel's width, height and refresh rate, and the DRM driver fails a FBIOPUT_VSCREENINFO syscall with yres_virtual greater than the maximum supported value instead of letting the syscall succeed and setting yres_virtual based on yres.

2020-09-30serial: 8250_dw: Fix clk-notifier/port suspend deadlockSerge Semin
It has been discovered that there is a potential deadlock between the clock-change-notifier thread and the UART port suspending one: CPU0 (suspend CPU/UART) CPU1 (update clock) ---- ---- lock(&port->mutex); lock((work_completion)(&data->clk_work)); lock(&port->mutex); lock((work_completion)(&data->clk_work)); *** DEADLOCK *** The best way to fix this is to eliminate the CPU0 port->mutex/work-completion scenario. So we suggest to register and unregister the clock-notifier during the DW APB UART port probe/remove procedures, instead of doing that at the points of the port startup/shutdown.

2020-09-30serial: 8250: Skip uninitialized TTY port baud rate updateSerge Semin
It is erroneous to update the TTY port baud rate if it hasn't been initialized yet, because in that case the TTY struct isn't set. So there is no termios structure to get and re-calculate the baud if the current baud can't be reached. Let's skip the baud rate update then until the port is fully initialized. Note the update UART clock method still sets the uartclk member with a new ref clock value even if the port is turned off. The new UART ref clock rate will be used later on the port starting up procedure.

2020-09-30tty: serial: imx: disable TXDC IRQ in imx_uart_shutdown() to avoid IRQ stormMatthias Schiffer
The IPG clock is disabled at the end of imx_uart_shutdown(); we really don't want to run any IRQ handlers after this point. At least on i.MX8MN, the UART will happily continue to generate interrupts even with its clocks disabled, but in this state, all register writes are ignored (which will cause the shadow registers to differ from the actual register values, resulting in all kinds of weirdness). In a transfer without DMA, this could lead to the following sequence of events: - The UART finishes its transmission while imx_uart_shutdown() is run, triggering the TXDC interrupt (we can trigger this fairly reliably by writing a single byte to the TTY and closing it right away) - imx_uart_shutdown() finishes, disabling the UART clocks - imx_uart_int() -> imx_uart_transmit_buffer() -> imx_uart_stop_tx() imx_uart_stop_tx() should now clear UCR4_TCEN to disable the TXDC interrupt, but this register write is ineffective. This results in an interrupt storm. To disable all interrupts in the same place, and to avoid setting UCR4 twice, clearing UCR4_OREN is moved below del_timer_sync() as well; this should be harmless.

2020-09-30serial: 8250_fsl: Fix TX interrupt handling conditionAndrij Abyzov
This is the port of the commit db1b5bc047b3 ("serial: 8250: Fix TX interrupt handling condition") to the 8250_fsl irq handling logic. Interrupt handler checked THRE bit (transmitter holding register empty) in LSR to detect if TX fifo is empty. In case when there is only receive interrupts the TX handling got called because THRE bit in LSR is set when there is no transmission (FIFO empty). TX handling caused TX stop, which in RS-485 half-duplex mode actually resets receiver FIFO. This is not desired during reception because of possible data loss. The fix is to check if THRI is set in IER in addition of the TX fifo status. THRI in IER is set when TX is started and cleared when TX is stopped. This ensures that TX handling is only called when there is really transmission on going and an interrupt for THRE and not when there are only RX interrupts.
